It seems to be mapped properly, that is, if I grab the "ContentControl"
object for the image and check XMLMapping.CustomXMLNode.XML it returns as I
would expect.... but in the document, the image will not update.
Is there something I'm missing? According to the help file I was reading,
http://msdn.microsoft.com/en-us/library/bb266219.aspx, it says it's supported
but I can't, for the life of me, get it to work.
